Tecra A11 - No Video via mini DisplayPort

Hi There,
I just recently purchased a mini DisplayPort -> HDMI cable to be used with my Tecra A11 Notebook. My intention was to run two external displays by running a VGA cable to my LG W2242 Monitor and run the mini-DP to HDMI cable to my HP 2509m Monitor. Unfortunately I cannot get my HP monitor to recognize the Video Signal from the mini DIsplayPort.
I have downloaded the newest drivers for my laptop, but still no luck. Is there anything special I need to do to get the mini DisplayPort to send a Video Signal?
Any help would be greatly appreciated.
Regards,
Landon

The Tecra A11 I have purchased (the A11-00N) only has two external video ports; A mini DisplayPort and a VGA.
I am currently running the Tecra A11 hooked up via the VGA Port to my HP 2509m Monitor. When unplugging the VGA cable and attempting to use just the mini DisplayPort to attach a SINGLE external Monitor I still have trouble getting a signal.
@Andrej - I'm currently attempting to attach 2 external monitors while closing the lid of the built-in display. In any case this should work as the laptop would still be only running 2 displays total.
What troubles me is that the mini DisplayPort doesn't work in a single display setup. I am going to attempt using the cable with a MacBook Pro later today and hopefully it will help in pointing to the root of the problem.

Tecra A11 - No Video via mini DisplayPort

Hi There,
I've recently aquired a Tecra A11 through my company that has two external video ports: VGA and mini DisplayPort.
With my previous laptop I ran two External displays while the laptop was closed and I would like to achieve this with my new Tecra A11. In attempts to achieve the same setup I have purchased a mini DisplayPort to HDMI cable from MonoPrice.com.
Unforunately when trying to use the mini DisplayPort->HDMI cable with the HP monitor I cannot manage to aquire a signal or get anything to display. This happens both when trying to run dual monitors miniDP/VGA and when I only try to run a single external display with the mini DisplayPort to HDMI cable.
I have downloaded the latest Video Drivers for the Tecra A11 but it still cannot see the External Monitor through the mini DisplayPort. Is there something special I have to enable in order for the mini DisplayPort to pump out a signal? or am I missing something here?
Any help would be greatly appreciated as I greatly miss my large monitors.

Lando

Hello Lando,
I have exactly the same problem with an S11-160 Tecra laptop. Did you find any solution ??
Thanks

2009 24-inch iMac 3.06GHz (EMC no. 2267). I don't get any audio when connecting my Sony HD TV to my iMac via mini DisplayPort. Is there a fix or hardware upgrade? I'm using a Kanex Mini DisplayPort to HDMI cable w/ audio support.

You can connect the audio from your iMac to your TV using a mini jack (like headphones plug) to rca (regular red and white audio connectors used on every TV,DVD, etc) cable.
On your TV, you need to be able to set the audio for the HDMI input you will use to "analog" and connect the rca end of the cable to the analog inputs on your TV.

Connect Mid-2009 Macbook Pro to HDTV via Mini Displayport to HDMI adapter

Hello,
I'm trying to connect my Mac to my HDTV via a Mini Displayport to HDMI converter I bought at the Apple Store. I have tried on three different HDTVs, none of which allow me to output video. I have tried adjusting the resolution to every available resolution under system preferences. Any advice as to how to resolve this problem would be very much appreciated.
Thank you,

I'm having the same problem, also with a 2009 13" MBP and a Mini DisplayPort to HDMI adapter. Does anyone out there have a solution? Do we need a different kind of adapter? My tv is a Samsung 720p. My boyfriend can connect his PC laptop with an HDMI cable with no issues.

No audio via Mini DisplayPort to HDMI Adapter

I have a late 2008 model (MB470LL/A) 15" MacBook Pro running 10.6.7.
I purchased a Dynex Mini DisplayPort to HDMI Adapter that's not picking up the audio signal. The video plays fine via HDMI to our TV, but no audio.
In looking online I've seen this is a known issue. Has anyone discovered a work around other then running a separate audio cable from my computer to the TV?
I'm really surprised there is no audio this way. Someone dropped the ball on this one.

I might be wrong but the MBP 2008 does not have audio supplied capability over MDP to HDMI.

IMac 27" (Late 2009): getting audio to HDMI receiver via mini DisplayPort

I just got my first iMac 27" and I'm in the process of integrating it into my home theater system. Here is my setup:
iMac 27" connected to HDMI receiver (Yamaha RX-V1800) via mini DosplayPort, using miniDP-to-HDMI adapter + HDMI cable
Optoma HD20 video projector connected to HDMI receiver (HDMI out) via HDMI cable
I have Windows 7 installed via Bootcamp 3.2, so that I can take advantage of Windows Media Center. With the above setup, I am not getting audio or video signal to my receiver and video projector when I'm using Windows 7. However, when I am in OS X environment, I can get both video and audio signal to my receiver and video projector, and either mirror or extend my video diplay. When I do plug in my iMac straight into my video projector or LCD monitor with built-in speakers while in Windows 7, I get both audio and video output. So why doesn't it work -- and only under Windows 7 -- when the signal goes through the receiver?
My immediate thought was that it must be something about the receiver, but since the setup creates no problem under OS X I don't think it is. Could it perhaps be the Windows driver for mini DisplayPort, because it looks like iMac is not 'recognizing' my receiver and therefore not establishing connection? Is there a driver of fix available that takes care of this problem?
Thanks!

I've tried a few times and it hasn't worked so far...
23" Cinema Display (ADC) connected to Apple's ADC to DVI adapter/power box then connected to Apple's DVI to mini Display Port adapter.
Trying to output extended desktop from iMac to 23" Cinema Display.
No signal or anything on the 2nd monitor so far.
USB port on Cinema Display works with the setup.
Checked system updates and all up to date as of 01-10-2010.
OS X 10.6.2 build 10C2234

Problems projecting W530 via mini-displayPort to HDMI TV

I am having problems attempting to project to a TV connected via HDMI to my W530 using a mini-DisplayPort to HDMI conversion cable. The TV goes into an initializing connection mode then states unsupported format. I have tried discrete and Optimus video modes in the BIOS, but for the life of me I cannot project to my HDMI TV. Any ideas?

What cable or adapter are you using? I have no need for that particular conversion so I have not tried, but if I were going to, I would probably use http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10428&cs_id=1042802&p_id=5311&seq=1&for... for starters.
Usually monoprice products work well enough and their prices rock.

No audio via Mini-DisplayPort. MBP 5,5

Hello,
I have the MBP 5,5 and I am trying to connect it to my TV via the Mini-DisplayPort HDMI adpater.
I am getting video but not audio any idea?
Any help is appreciated.

A 2009 MBP does not support audio via the minidisplay port. For audio you will have to tap the audio output port and use RCA connectors to the audio inputs on the TV.
Ciao.

Connecting two 27" iMacs via mini DisplayPort

Juz a thought. Wonder if possible.
Since the 27-incher iMac does video input and output, instead of buying two 30" displays ($1799 each), might as well buy two of these 27" iMacs ($1999 each) and connect them via their mini DisplayPorts. Wonder if it's possible to use one 27-incher for computing and use the other as a second monitor, and switch around whenever it's needed. Kinda cool to have two 27-inchers and Macs on one table top.

There is no reason why that would not work. It would be the same as connecting a MacBook or a Mac mini or a Mac Pro (any Mac with a Mini DisplayPort) that same way to use the 27-inch iMac's big screen as a second display, which is the primary purpose of this feature. It should not matter if the primary Mac happens to be another 27-inch iMac.
And the second iMac would not be "just the display to extend my screen." It is fully operational, so it can be doing tasks in the background. It can be acting as a file or web server, or processing video, or downloading/uploading files. I believe there is a keystroke to toggle the display, and you can probably even control it using +Screen Sharing+ from the other iMac (as long as the two are connected over a network).
What would be really interesting to know, from someone who actually has two of these iMac sitting side-by-side, connected with a Mini DisplayPort cable, is if you can use either iMac as the extended Desktop screen for the other iMac, on-the-fly. So you'd be working on iMac A with iMac B being the second display. Then, you switch to the working on iMac B with iMac A being the second display. And do it with a few keystrokes and no rebooting. Now, that would be cool.

No sound on HP Envy 32 via mini DisplayPort to DisplayPort cable on Mac mini

I recently bought an HP Envy 32 monitor and hooked it up to my Mac mini using a mini DisplayPort (i.e. Thunderbolt) to DisplayPort cable. The video works fine @ 2560x1440, but I have no sound. The sound output in system preferences mentions "The selected device has no output controls" for the Envy 32. The sound works fine when I use an HDMI cable, but then the resolution is limited to 1080p. The Mac mini is a mid 2011 model, which is capable of transferring audio via DisplayPort, as far aas I know. Any suggestion on how to solve this?

you should try mirroring your screen on the Vizio HDTV

Connecting my macbook pro 13" to Sony bravia via mini Displayport to HDMI

Hi,
yesterday I bought a new LCD TV Sony Bravia KDL-32EX600 (Full-HD LED) that has 4 x HDMI inputs.
I also bought a mini Displayport to HDMI and HDMI to HDMI cable.
When I connect it to my computer, the screen goes blue for a second and it doesn't recognise any additional displays. There's also no video or sound in the TV, on the right HDMI channel. (I've tried every HDMI input and every channel)
I've tested the TV with another laptop that has straight HDMI output from the gfx card and it works perfectly.
I have up-to-date MacOS and I also upgraded my TV's firmware to the latest.
I thought that maybe the miniDisplayport to HDMI connector is broken but why does the computer try to do something when I turn on the correct channel on the TV?
I'm out of ideas..

Hi madhenry,
I know it's a month on from your post, but I thought I'd add that I'm having exactly the same problem. I'm trying to connect my new MacBook Pro (15" core i7) to my Sony Bravia KDL-40EX600 using a mini displayport to HDMI adapter. When I plug the cable in, the MBP screen goes blue for one second then goes back to normal, but the system just doesn't detect the external display.
I've tried the MBP on other monitors and it works fine, so there is nothing wrong with the adapter or cable.
I've also tried plugging two other Macs into the TV (a 2008 15" MacBook Pro and a 2008 MacBook) and the TV works great with both of them.
So, it seems there's something specific to the new MacBook Pros that makes them incompatible with the Sony EX600 TVs.
I just talked to AppleCare about it and after trying a few things (resetting the PRAM, etc.) I was simply told that there's nothing wrong at all with the Mac and that this is simply a "compatibility" issue that I have to put up with. So, it looks like we're out of luck until (hopefully) a new Mac OS update fixes the issue.

No Video from Mini-DisplayPort or DVI, only Dual-Link DVI

Just got my new Mac Pro 6-Core delivered. Out of the box, there were problems. I have a Dell 27" monitor that takes Dual-Link DVI, DisplayPort, or HDMI and a Dell 22" monitor that takes DVI, VGA, or HDMI. I am using a DisplayPort to Mini-DisplayPort cable to connect my 27" monitor to the Mac Pro and a DVI cable for my 22" monitor. I have the ATI 5870 graphics card installed OEM.
The problem is that the graphics card appears to not be switching to Mini-DisplayPort or DVI for output. It only works when I plug in a Dual-Link DVI cable to my 27" monitor. At that point, I get a video feed on my screen on a hard boot. At this point, I can then plug in my Mini-DisplayPort cable to my Mac Pro and unplug the Dual-Link DVI cable, and it switches video feeds perfectly. The problem then is that when I restart the computer, or power off and power on, the problem starts all over again. I HAVE to boot using the Dual-Link DVI cable for anything to work.
Ideas? Called AppleCare, waiting on engineering to see what they have to say. All the cables work perfectly when I plug them into my MacBook Pro (Late 2008). I am stumped.

I seem to be having similar problems. I bought the same system (6-core Westmere with the 5870 graphic card installed OEM) last month and I seem to be having problems running two Dell monitors which I know to be perfectly fine.
For the past month, I've been using a 24" Dell U2410 monitor with my Mac Pro using a DVI cable. Absolutely no problems at all. I then purchased another 24" Dell U2410 with the intention of running with dual displays. To prepare for this, I bought two mini-DisplayPort to DisplayPort cables from Monoprice. When I finally received the second display, I turned off the computer, hooked up both monitors through DisplayPort using the two mini-DisplayPort connections on the graphics card and turned on the system. I got two black screens. I tried to use keyboard commands to bring up the shutdown dialog box but it wasn't working. So I was forced to do a hard shutdown by holding down the power button for 10 seconds.
I went through a series of combinations of power cycles for the displays and computer and still two black screens. Finally, I went back to square one, a single display through a DVI cable. Again, a black screen. At this point, I disconnected the display from the computer. Power cycled the display (this initiates the self-test for the Dell display), hooked it up to the Mac Pro, turned it on, and it worked. I had one working display. Then I plugged in the second display using the mini-DisplayPort to Display port cable and that worked also. Finally, two working displays. For some reason, the Mac Pro recognized the display using the DisplayPort as the primary monitor. I rebooted the Mac Pro and the monitors continued to work properly. I booted into Windows 7 and again, no problems. I went back to OS X and used the computer for the night. When I was done, it put it to sleep.
This morning, when I tried to wake it up, same problems. I had to go through a series of power cycles and cable swapping to finally get a single screen to work.
I went through some of the troubleshooting documents here in the Support area and found this one:
http://support.apple.com/kb/HT4279
I am going to pick up the Apple mini-DisplayPort to DVI adapter and try running the display as two DVI monitors. Hopefully this will fix those problems. If the AppleCare engineer is able to give you anymore information, please let us know. This is a worrisome issue.

NTSC monitor component/RGB to Imac via min-displayport

I'm trying to hook up an NTSC monitor which only has RGB and component (Y, R-Y, B-Y) ports to my 2009 iMac, which thus must use a min-display port to do so.
Does anyone know of the best way of connecting this NTSC monitor to my iMac? I had thought about...mini displayport/DVI-->DVI to component.
Although mini displayport/VGA-->VGA to component might work too.
One concern I had was that I heard the mini displayports were DVI-D opposed to DVI-I, which may or not mean a component adapter would work.
help lol.
thanks

There was a long thread on the forum with good info regarding conversion of Mini DisplayPort to composite/S-Video.
http://discussions.apple.com/thread.jspa?messageID=9692969
I don't think component will work for the same reasons, unless you use something like the rather complex method explained in the post by Lougle in the above thread (the one with pictures). Maybe it is different...
I thought of something the other day though. OWC has a recent USB video adapter product.
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
I wonder if you could put a DVI-to-component adapter (or a DVI-to-composite adapter) at the end of this USB-to-DVI adapter, and get it to work. I don't think the product description has the answer, and I was going to send an email to OWC's sales/tech support to ask. I'm only curious, since I don't need such an output myself. If you decide to ask them, please post back with their response.

Can I watch an iTunes movie rental on a TV connected via mini displayport?

I'm not sure if there's been any headway with this, but I've got a mini displayport to HDMI adaptor on the way that I'm going to use to connect my MacBook Pro to my HDTV, effectively using the TV as an external monitor.
And of course, I want to watch some iTunes movie rentals on the TV instead of my laptop, but digging around the internet has shown that I might be facing an issue relating to the HDCP standard that would prevent me from being able to use my TV in this manner.
Is this still an issue? I have a fall 2009 MacBook Pro, which may be important, as I've read that Apple modified the mini displayport on the MacBooks in 2010.
Other than renting a movie as a sort of guinea pig with the possibility of being shot down and wasting my money, is there any way to know if this is going to work? Or is it simply a fact that any monitor/TV connected to my MacBook through the mini displayport is incompatible with HDCP, and I'm totally out of luck?
(Which, FYI Apple, is utter horse **** and is absolutely counter-productive to the notion of encouraging me to pay for digital entertainment.)
What are your thoughts, folks?

If your HDTV is HDCP compliant, you probably will have no problems. But you might want to read this information which while written a while back still, to the best of my knowledge, applies:
http://www.ilounge.com/index.php/articles/comments/16488
HDCP compliance is, from what I've read, rather a "rubber ruler" so even if your TV lists as being HDCP, it might or might not work correctly with your Mac. Testing with one movie first might avoid an expensive surprise.
As to your complaint to Apple, it probably wasn't up to Apple but instead was forced on them as part of the conditions by the content owners for licensing movies and shows to the iTunes Store. But feel free to comment to Apple via their feedback pages:

Online conference participants hear echo when cinema display is connected via mini-displayport, even though I am using headphones with mic.

When I use Google Hangout or GoToMeeting, other participants in the meeting hear an echo of their sound -- loud and obtrusive. When I mute, it goes away.
This only happens when I am using my Apple Cinema Display 27" (recent vintage) connected via the mini-displayport (natively, not an adapter).
On my end, i don't hear their echo, but I do hear waves of squelching -- basically it sounds like their end is trying to adjust their input down to account for what it thinks I saying, even though I'm not talking, it's just the echo making that happen.
Sometimes this doesn't occur -- it seems to crop up intermittently, but happens around 75% of the time at some point in a conversation.
I am using iPhone-compatible in-ear earphones with built-in mic; the earphones are the rubber seal type, so there's no sound escaping them that the system should even be able to hear.
I have my audio set up for "Headphones" as output device.
Input device is set up as "External Microphone" -- this part confuses me because even though I know my Cinema Display has a microphone, the OS seems not to list it as a separate input device. So I wonder if it's getting confused trying to use both the cinema display's mic *and* the earphone mic? (see dropdown image)
OS version 10.20.2; Macbook Air 13 inch, "early 2014" and Apple LED Cinema Display 27inch
Earphones are skull-candy brand iPhone compatible (with built-in mic), plugged into the macbook air's earphone jack. (without the display connected, this has always worked fine -- and with a prior non-apple display that had no mic/camera this was not a problem)
This is an ongoing issue in our office, in fact ... especially troublesome in client meetings.
I haven't tried other configurations, other than when using the Cinema Display's USB connector, the same thing happens.
It also happens even when I'm not using the "USB PnP Sound Device" you see listed in the dropdown here -- that's something I use for controlling music output to my desk speakers.
A general question: is there no way to control the cinema display's mic and/or camera more directly?
(EDITED TO ADD: Ok I see in the Cinema Display manual, there should be a listing for "Display Audio" in the input list, but my SysPref panel has none listed. See other screenshot. I wonder if this is the problem??)

Curious, is the 30-inch Cinema Display you have, one listed in this Support Article:
•Apple Cinema Display (20-, 23-, and 30-inch DVI) - Technical Specifications
or is yours a later build series; which one do you have...? This says Mini unsupported.
The specifications vary across the line of Displays, as do the graphic support in Macs.
I'd suspect your version is a later 30-inch display, but it may be one of these. And a
newer 27-inch Display has the Thunderbolt cable.
In any event...
Good luck & happy computing!
